My pcp suggests i try voltaren (diclofenac) gel on my penis to help with ed due to arterial blockage. my urologist says there's no harm in trying. opinions?

Do not use it: The use of voltaren (diclofenac) gel in this issue makes no sense. It has no value and is not meant for use on a penis.

I agree: If you've tried it using the gel before and there is no allergy to it, you can try. I have never known it to work for that purpose nor is there a study for that but if it works for you, then you can help others..
